Title:
VIBRATOR AND PORTABLE TERMINAL DEVICE MOUNTED WITH THE VIBRATOR
Document Type and Number:
WIPO Patent Application WO/2004/078366
Kind Code:
A1
Abstract:
A structure of a vibrator to increase reliability in an electrical connection between power supply terminals of and circuit board electrodes of the vibrator, and to improve mounting efficiency of the vibrator on a circuit board. In the structure, the terminals are constructed from twisted coil springs, and contact portions of the terminals, which portions are in contact with the electrodes, are made in a winding form. The twisted coil springs each are wound around a pivot pin, and steps as clearance for the contact portions and surface portions to which the contact portions are opposed face to face are provided. However, alternatively to the steps and surface portions above, any of the following structures can be adapted: providing a partition plate between two power supply terminals, or surrounding spaces, in which the contact portions can elastically deform, by insulative box members, or extending the twisted coil spring portions to the contact portions asymmetrically in a positive and a negative electrode so that, when the power supply terminals are elastically deformed, each of the contact portions to be deformed more outward than each of the coil spring portions.
